Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability in the CLI of Cisco SD-WAN Software could allow an authenticated, local attacker to overwrite and possibly corrupt files on an affected system. This vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by injecting arbitrary commands that are executed as the root user account. A successful exploit could allow the attacker to overwrite arbitrary system files, which could result in a denial of service (DoS) condition.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the Cisco SD-WAN product in use
    Log into the device or check system documentation to determine which SD-WAN component is deployed (vManage, vBond, vSmart, or Catalyst SD-WAN Manager)
    Affected if The product is any of Cisco SD-WAN vManage, vBond, vSmart, or Catalyst SD-WAN Manager
  2. Determine the installed software version
    Use the CLI command 'show version' or access the web UI dashboard to retrieve the currently running software version number
    Affected if The installed version matches any of these: 20.8, 20.9, or any version earlier than 20.6.2 (for the applicable product)
  3. Confirm CLI access is available
    Verify that CLI access is enabled and accessible, typically via SSH to the device or console connection
    Affected if CLI access exists and the attacker can authenticate as a local user
  4. Check for local authenticated user access
    Review the list of locally configured users on the device using 'show users' or user management commands in the CLI
    Affected if Local user accounts exist on the system, providing an authenticated attack vector
  5. Identify the vulnerable command interface
    Examine which CLI operational or configuration commands accept user-supplied input that could be leveraged for injection
    Affected if The device runs an affected version and accepts unauthenticated or weakly secured CLI input

The environment is likely affected if any Cisco SD-WAN component is running version 20.8, 20.9, or any version prior to 20.6.2, and local CLI authentication is accessible.

Upgrade available Upgrade to 20.6.2 or later
Fixed in 20.6.2
Interim mitigation

Apply Cisco's available patches for CVE-2022-20930; restrict CLI access to trusted local users only until the patch is applied.

Recommended fix Moderate confidence

Upgrade to 20.6.2 or later; for vManage/vBond/vSmart, 20.6.2 contains the fix. For 20.8/20.9 users, obtain subsequent security update from Cisco.

  1. 1. Identify the specific Cisco SD-WAN product in use (vManage, vBond, vSmart, or SD-WAN Manager)
  2. 2. Determine the currently installed version via CLI using 'show version' or the administration interface
  3. 3. For versions < 20.6.2: Plan upgrade to 20.6.2 or later stable release
  4. 4. For versions 20.8 or 20.9: Check Cisco release notes for subsequent security updates addressing this vulnerability
  5. 5. Schedule maintenance window as upgrade will require system restart
  6. 6. Back up current configuration before proceeding with upgrade
  7. 7. Obtain upgrade software from Cisco directly via official channels or Cisco Software Central
  8. 8. Follow Cisco SD-WAN upgrade procedure documented in the migration guide for your specific product
Caveat Standard SD-WAN upgrade may cause brief service interruption; ensure valid configuration backup before proceeding
